明天会发上周普化小考
CH3CSNH2 + H+ + 2H2O→CH3COOH + NH4+ + H2S(aq)
CuS, Bi2S3 + NO3-→ Cu2+, Bi3+ + S↓ + NO↑
2Bi(OH)3(s) + 3Sn(OH)3- + 3OH- → 2Bi↓ + 3Sn(OH)62-
SbS33- + H+ → Sb2S3(s)
Sb2S3(s) + H+ + Cl- → 2SbCl4-(aq)
SnCl62- + 3H2C2O4 →Sn(C2O4)32-
SbCl4- + H2S → Sb2S3
Sn2+ + 2HgCl2 →Hg2Cl2(s) + Sn4+ + 2Cl-
Bi3+ 2Bi3+ + 3S2- → Bi2S3(s)
Bi2S3(s) + NO3-→ Bi3+ + S(s) + NO(g)
Bi3+(aq) + OH- → Bi(OH)3(s)
2Bi(OH)3(s) + 3Sn(OH)3- + 3OH- → 2Bi(s) + 3Sn(OH)62-
Cu2+ Cu2+ + S2-→ CuS(s)
CuS (s) +NO3-→ Cu2+ + S(s) + NO
Cu2+ + 4NH3→ Cu(NH3)42+
可能有人没抄到 也有可能有人天赋异秉自己就会
不管怎样请享用
(谢谢全国帮忙打讲义的化学老师,经过这一晚我终於知道您的辛勤 )
(谢谢成功高中黄财堂老师,原来很认真的老师)
101A1 03 Problem Set 7
11/4/2008 in class.
1. (10 points) A spherical shell has inner radius R1, outer radius R2, and mass M, distributed uniformly throughout
the shell. What is the magnitude of the gravitational force exerted on the shell by a point particle of mass m
located a distance d from the center, outside the inner radius and inside the outer radius?
2. (10 points) Each of the four corners of a square with edge a is occupied by a point mass m. There is a fth
mass, also m, at the center of the square. To remove the mass from the center to a point far away, what is the
work that must be done by an external agent?
3. (10 points) Without neglecting the revolution of the earth, calculate the escape velocity from the surface of the
earth at the latitude north 25 degree. (take the radius of the earth 6370 km and the mass of the earth 5:981024
kg)
4. (10 points) problem 99 in chapter 13
5. (10 points) problem 56 in chapter 13
6. (10 points) problem 21 in chapter 14
7. (10 points) A bucket contains the water of half of its full volume. Now, the bucket is rotating with the angular
velocity ! and the surface of the water forms a certain shape. Show that the shape satises the following relation
h(x) = !
3g x3, where h is measured from the lowest of the surface and x is measured from the rotational axis.
8. (10 points) problem 65 in chapter 14
9. (10 points) problem 72 in chapter 14
10. (10 points) problem 48 in chapter 14
由於处於金属和非金属中间，同时具有两者的特性。 作为金属，可氧化至二价锡和较稳
家的四价锡。二价锡是两性的，在酸中，可形成 [SnX3]-离子，X为F-,Cl-等；在硷中，
会形成[Sn(OH)3]-电浆。四价锡也是两性的，在酸中，可形成 [SnX6]2-离子，X为F-,Cl-
等；在硷中，会形成[Sn(OH)6]2-, [SnO3]2-电浆。四价锡的溶液都倾向水解出SnO2沉淀
。 作为非金属，锡可和碳，氧等非金属组成份子。尤其是碳，可和锡形成很多有机锡化
合物，应用很广泛。
